Nesting partner
A nesting partner is someone you live with and share a home life with, whatever the wider shape of your relationships.
A nesting partner is a partner you share a home and daily life with — the person you "nest" with. The term is common in polyamory because it describes a living arrangement without implying that this partner outranks all others.
Sharing a home brings its own intimacy: routines, finances, chores and rest. A nesting-partner relationship often carries real practical entanglement even where a couple chooses not to label anyone as primary.
Using the term lets people acknowledge the realities of cohabitation honestly, while still leaving room for other meaningful relationships. It pairs naturally with conversations about time, boundaries and fairness across a network.
